MASON – An Illinois excavation company has filed a $1.2 million construction lien against Enbridge Pipelines and Enbridge Energy for work done at a Stockbridge Township storage tank farm under a $5.6 million contract.

The lien was recorded in Ingham County on Tuesday and states Witech Co. Inc., of Crete, Illinois, worked from June 2014 through May 2015 on land owned by the Enbridge affiliates, which are based in Superior, Wisconsin.

The lien said Witech was paid $4.4 million. The lien provides few other details other than a reference to Witech having furnished “labor and/or material” to Matrix SME of Eddystone, Pennsylvania, “for construction of KBBL tanks and associated grading in connection with improvements to” property in southeast Ingham County.

Maxtix SME also is named in the lien, but the property encumbered by the lien is owned by Enbridge Pipelines, according to county tax records.

KBBL is an industry term for storage tanks. An aerial map shows the land to be a tank farm. Enbridge added storage capacity near Stockbridge as part of a $2.6 billion replacement of its Line 6B crude oil pipeline.

The line had ruptured in 2010 and dumped about 800,000 gallons of crude oil into the Kalamazoo River system. The replacement project stretched 285 miles between Lake County, Indiana and Marysville, Michigan. The new pipeline went into service last Oct. 1.

The lien suggests Witech Co. was a subcontractor to the Enbridge affiliates and to Matrix, but Witech owner Tom Witvoet declined the State Journal’s request to explain the pay dispute.

“I’d like to keep that between us (Witech and Enbridge) at this time,” he said.

Lansing attorney Michael Matheson filed the lien but said he was not authorized to comment.

Enbridge officials in Superior said they would research the dispute and get back to the LSJ but did not do so by late Thursday.

The Enbridge website says restoration of the pipeline right-of-way is nearing completion.

Three people were convicted of trespassing and obstructing police for protesting the pipeline project. They were sentenced in March 2014 to time served in the Ingham County jail and 13 months’ probation. The three were arrested July 22, 2013 and convicted in January 2014.

The Enbridge subsidiaries’ parent company is based in Calgary, Alberta.
